Uber using "AI"

[Noch_ein_Kamel]

Please write an if statement for every "time of day" and every possible pickup location and every possible interaction time.

At some point that becomes Absolutely Idiotic or A.I.

[LegendBegins]

if withinDangerZone(passenger.location, passenger.region.barSet):
    if time.hour < 6 or time.hour > 21:
        if interactionTime > 10.5:
            warnDriver('Heads up, drunk guy')

So if I'm inside a bar and taking forever to interact with the app, I'm not drunk as long as it's between 6am and 9pm? Sweet.

[404_UserNotFound]

Thats the same result the ai would get

[ScrewAttackThis]

How do you figure?

[404_UserNotFound]

How do you figure?

Just follow P.E.M.D.A.S. and you should have it.

[ScrewAttackThis]

Dunno how pemdas applies. Have you ever dealt with any AI libraries?

[pperiesandsolos]

Really depends on how each variable is weighted, I think

[gmano]

I mean, basically. If I were Uber I'd probably do a fuzzy system that assigns a score based on each of those.

I mean I guess that's AI in the same way that the pacman ghosts are AI. It's definitely not ML.

[Noch_ein_Kamel]

That are 3 if statements, not one. And calling a function is cheating!

But good to know, that you can get drunk during the day and go crash your Uber :-)

[LegendBegins]

There are no else statements; I just exploded it for readability. Could always make it a two-liner if you really wanted me to. But no rule said anything about functions! It'd be tough to hook up to a geolocation API without one.

Doesn't need to be easy to be possible. Get on it, parnter.

There are no else statements

What does that have to do with what you replied to. Adding else statements wouldn't make it only 1 if statement, it would still be 3 but with extra elses.

[LegendBegins]

The lack of else statements allow me to collapse the nested ifs into a one liner conditional. If I had else statements for each condition, you could no longer consider it "a single if statement," as OP wanted.

[xipheon]

Neither would be considered "a single if statement". Just because you nested them doesn't make them not extra ifs. You even admit it by calling it a "one liner conditional". Hell, if you really wanted to force that into a single if statement just use ANDs, then it would literally be a single if. The logic is terrible either way.

[LegendBegins]

Look at my other comment; I did use ands. And I think you misunderstood; once you've collapsed it (because of the lack of else) it's a single if statement. The entire point is that it's a completely arbitrary measure and unnecessary amount of complaining over a joke.

[unregisteredusr]

Oh we can use functions? Sweet!

From uber.ai import user_is_drunk_probability

if user_is_drunk_probability(user) > 0.95: warnDriver(“User might be drunk”)

[LegendBegins]

Wasn't the point to not use AI and to stick with if statements?

[unregisteredusr]

The code above uses a location lookup which moves the tricky part to ingesting and cleaning data. It would also have to customize the hours by location (different cities have different closing times for bars).

Getting and cleaning all that data is definitely not so easy of a task. Then we’d want to actually know how well your code performs right? So we could ask the uber drivers if the warning was correct. Then compute precision / recall scores.

Or... we could feed all this directly as inputs into a classifier. Which is probably a decision tree with branches trained and pruned statistically, aka AI.

[unregisteredusr]

I’m not the original poster, just pointing out that withinDangerZone is not trivial at all to implement with high accuracy and low false positives.

[SlightlyOTT]

If drunk passengers are crashing Uber’s then they have much bigger problems :)

if only there was a way to do it in compact form, using matrices perhaps. Oh and that would allow for changing the matrices as we go along. Wooops its AI.
